Like Kate, Kim is also a mother to three sweet kids, North, 4, Saint, 2, and Chicago, three months, with husband Kanye West. The KKW Beauty guru posted a snapshot of her and her family on a plane, enjoying some quality time together.

Kanye flashed a rare smile while holding baby Chi in his lap, as Kim cuddled up close to Saint, clad in full-on camouflage, and North, who has seemingly learned some poses from her famous mama.

Meanwhile, in London, Kate and William, who are also parents to 4-year-old Prince George and 2-year-old Princess Charlotte, posed for photos outside of St. Mary's Hospital shortly after their newborn's arrival. The two have yet to reveal the name of royal baby No. 3, but according to Kensington Palace, the baby boy will travel home with Kate and William Monday evening.
